PHOTOGRAPHIC-PRINTING FRAME.

Specification of Letters Patent.

Patented June 16, 1908.

App1ication filed .Tune 17, 1907. Serial No. 379,391.

T 0 all. whom it may concern: Be it known that I, JOHN zen of the UnitedStates, and a resident of Burlington, Racine county, Wisconsin, haveinvented certain new and useful Improvefrom its position, and therebymove from its relative position to the negative, substantially ashereinafter fully described and as particularly pointed out in theclaims.

In the drawings :Figure 1 is a rear view of a printing-frame having myimprovements applied thereto. Fig. 2 is a longitudinal section taken ondotted line 2, 2, Fig. 1. Fig. 3 is a transverse section through onelongitudinal member of the frame taken on dotted line 3, 3 Fig. 1.

Referring to the drawings A represents the usual rectangular open frame,the inner edges of the sides of which, adjacent to the front areprovided with the usual ledges a, and the longitudinal members of whichare thicker than the transverse members, and have their inner edgesprovided with longitudinal grooves b, which are in such a plane thattheir ends can be entered back of the plane of the rear edges of thetransverse members. At about'the center of length of each of thelongitudinal members of frame A a hole 0 is -bored therein from the reartowards the front, which, preferably, extends to or nearly to the ledge"filler d is inserted in each of said holes, until its rear edge isabout flush with the rear edge of said longitudinal member, and thentransverse slots 6, e, are made in any suitable manner from the inneredge of each longitudinal member and into said holes. The holes 0 andthe slots 6 opening into the same are in the same transverse plane, andwhile I prefer to locate them at about the center of length of theframe, their position will be governed by the hinge of the back B of theframe.

C. FYFE, a citifit a; a metallic tubular Back B corresponds to and isadapted to within the space inclosed by the longitudinal and transversemembers of .frame A with the marginal portions of its front resting onthe ledges a. The thickness of this back corresponds to the distancebetween ledge a and the rear surface of the transverse members of theframe, and it is divided into two sections, which are the transverseplane intersecting the holes 0, c. The hinge f connecting these twosections is, preferably, of the kind known as a piano hinge, and theknuckles of said hinge, which come between the opposing edges of saidsections, are connected by a wire pintle, the ends g, g, of which extendbe yond the sides of the back and are adapted to pass through the slots6, 6, into holes 0, c. The width of slots e is such that while theextended ends 9 of the pintle of the hinge. can freely enter the same,the back can have no longitudinal play.

Each of the sections has pivotally secured to the center of its rearsurface, a bow-shaped spring D, the ends of which normally bendoutwards, and which is of such length that when its ends are depressedtowards the back, and the spring moved into a transverse position, saidends will enter the grooves l), b, of the longitudinal members of theframe, and lock said section in position.

In 0 eration, the photographic negative plate 0' the proper size isplaced in the frame with its marginal edges resting on ledges a, a; thephotographic printing paper is then placed back of said plate and. thenthe back B is placed back of saidv paper and secured in place in themanner hereinbefore indicated. When it is desired to examine the print,the spring D of one section of the back is moved so that its ends arereleased from under the grooves l), and then said section can be swungrearward sufficiently to permit of the desired inspection withoutdisturbing the relative position of either the print or negative becauseof the engagement of the extended ends of the intle of the hinge withthe holes 0, c, in the rame.

IVhat I claim as new is 1. A photographic printing frame comprising arectangular frame having holes in its longitudinal members extendingfrom the rear towards the front surfaces thereof, a me tallic tubularfiller inserted in each hole, the said longitudinal members and fillershaving coinciding slots extending from the inner surfaces of thelongitudinal members to the holes, a sectional back for the frame, ahinge for the sections of the back, said hinge having a pintle extendinginto the slots of the frame and fillers, and means for holding the backin place in the frame.

2. A photographic printing frame comprising a rectangular frame havingholes in its longitudinal members extending from the rear towards thefront surfaces thereof, a me tallic tubular filler inserted in eachhole, the said longitudinal members and fillers having coinciding slotsextending from the inner sur faces of the longitudinal members to theholes, a sectional back for the frame, a hinge between the sections andfilling the space therebetween, a pintle for the hinge extending intothe slots of the frame filler, and means for holding the back in theframe.

3. A photographic printing frame comprising a rectangular frame, thelongitudinal members of which have grooves in their inner ed es, saidmembers being also provided with holes extending from the rear towardsthe front thereof, a metallic tubular filler inserted in each hole, thesaid longitudinal members and fillers having coinciding slots extendinfrom the inner surfaces of the longitudinaf members to the holes, asectional back, a hinge for connecting the sections of the back, apintle projecting from the hinge and extending into the slots of theframe and filler and means on the back slidable in the longitudinalgrooves for retaining the back in position.

In testimony whereof I have hereunto set my hand and seal this 1st dayof June, A. 1)., 1907.
